STEAM CONNECTION FOR LOCOMOTIVES.

Application filed October 20, 1922. Serial No. 595,758.

To all whom it may concern:

Be it known that 1, WILLIAM E. WOODARD, a citizen of the United States, residing at Forest Hills, in the county of Queens and State of New York, have invented certain new and useful Improvements in Steam Connections for Locomotives, of which the following is a specification.

This invention relates to steam connections for locomotives and is particularly useful in connection with locomotives having an outside dry pipe, as shown and described in my copending application, Serial No. 570,831, filed June 26, 1922, in which the subject matter hereof is generally indicated.

One of the primary objects of my invention is to provide an improved arrangement whereby the superheater header is relieved of any movement due to the motion of the locomotive, shocks and expansion strains.

Another object of the invention is to provide an anchor for the dry pipe and header; and a combined anchorage and cover plate or closure providing ready access to the superheater header.

Still another object is to provide improved means whereby access may be readily ad to the superheater header.

The foregoing, together with such other objects as may hereinafter appear or are incident to my invention, I obtain by means of a construction, the preferred embodiments of which I have illustrated in the accompanying drawings, wherein:

Fig. l is a fragmentary diagrammatic side elevation of a locomotive illustrating the application of my improvements thereto; Fig. 2 is an enlarged sectional view illustrating the details of my improvement; Fig. 3 is a section taken on the line 3-3 of Fig. 2; Fig. 4 is a side elevation of a detail of my improvement; Fig. 5 is a plan view of the forward portion of Fig. 2; Fig. 6 is a section taken on the line 6-6 of Fig. 5; and Fig. 7 is a section illustrating a slip joint utilized in carrying out my invention.

Referring now to Fig. 1, the locomotive A is provided with the usual front end B, composed of a suitable casing 7. The dry pipe 8 is located exteriorly of the boiler and extends forwardly from the dome 9, terminating short of the stack 10. The superheater header 11 is indicated in dotted lines and is provided with an elbow 12 extending upward through an aperture 7 which I provide in the top of the casing 7, the elbow virtue of the slot 15.

being connected with the dry pipe, as will hereinafter appear.

The anchorage means hereinbefore referred to comprises the sleeve member 13, provided with a flange 16, to which the corresponding flange 17 of the superheater elbow 12 is bolted; the flange 16 having a laterally extending arcuate flange or foot port izon 18 adapted to be bolted to the easmg The aperture 7 is of L-shape and provides access to the superheater header, which heretofore has only been accessible by removal of the front plate of the smoke boxan unsatisfactory arrangement because of the other parts in the box. A cover plate 15 of L-shape is provided for the opening 7 such plate beingcurved to correspond with the curvature of the front end, as will be seen on inspection of Figs. 5 and 6. The plate 15 is detachably secured over the opening by means of the clips 19 and it is provided with a slot 15 through which the elbow 12 extends.

-The elbow member 12 is covered by an elbow-like casing 14, suitably secured to the plate 15 and surrounding the top and sides of the elbow 12, the rear end thereof being secured to the flange 16 as by means of the studs 20. The anchor 13, the cover plate 15 and the casing 14 cooperate to form the closure for the opening 7 The member 13 constitutes an end for the dry pipe and it provides a secure anchorage for the dry pipe and the superheater header elbow 12, relieving the latter of shocks and strains as previously indicated. Expansion and contraction of the dry pipe is provided for by means of a slip joint 21, adjacent the dome, such as illustrated in Fig. 7.

Access to the header 11 may be had by loosening the clips 19 and removing the studs 20 when the members 14 and 15 can be slipped over the elbow 12 together by Access may thus be had to the interior without disturbing the dry pipe and the elbow 12 or the bolts which secure the flanges 16 and 17 together. The elbow 12 and the header may also be removed without disturbing the dry pipe.

Other advantages will occur to those skilled in the art.

.What I claim is:

1. In a locomotive, an exterior dry pipe member, a superheater header connection member, an anchorage for one of said members, a slip joint for the other member, and steam pipes leading to the cylinders.

2. In a locomotive, the combination of an outside dry pipe, a superheater header connection therefor, a combined anchorage for the pipe and said connection, and a slip'joint for the dry pipe.

.3. In a locomotive, the combination of a superheater header, a casing provided with an opening therethrough providing access to the interior, a dry pipe, and a dry pipe end member in part forming a closure for said opening.

4. In a locomotive, the combination of a superheater header, a casing provided with an opening therethrough providing access to the interior, a dry pipe, and a dry pi e end member in part forming a closure or said 0 ning said end member constituting an anc orage for the dry pipe.

5. In a locomotive, the combination of a superheater header, a casing provided with an opening therethrough providing access to the interior, a dry pipe, and a dry pipe end member in part forming a closure for said opening, said end member constituting an anchorage for the dry pipe and for the header.

6. In a locomotive, the combination of a casing1 provided with an opening, a superheater eader provided with an elbowextending through said opening, an outside dry ipe, and a dry pipe end member secure to the casing and forming a connection between the dry pipe and the elbow.

7. In a locomotive, the combination of a dry pipe, a superheater header, and a dry pipe end between the dry pipe and superheater header, said endconstituting an anchor for the dry pipe. y 8. In a locomotive, the combination of a dry pipe, a superheater header, and a dry pipe end constituting a combined anchorage for the dry ipe and header.

9. In combination, a dry pipe end comprising a flanged member adapted to be secured to the locomotive casing, a closure member and an elbow connected to the flange andthe closure members, the closure member and the elbow being removable independently of the flanged member.

10. In a locomotive, the combination of an outside dry pipe, superheater apparatus ada ted to be connected therewith, and a com ined anchorage and closure means including independently detachable members.

11. In a locomotive, the combination of a dome, a superheater header, an exterior dry pipe, a slip joint therefor, and a dry pipe end formlng an anchorage and connection for dry pi e and header.

12. In a locomotive, a smoke box,

a superheater header in the box,

the box being provided with an o ening afiording direct ac- WILLIAM E. WOODARD.
